I have been stuck on this problem for a while, and wonder if anyone knows the answer. It is concerning accessing some properties of a custom component. I marked the problem with the keyword [PROBLEM] in the following snippets of code.
components/State1UI.mxml
--------------------------------
<?xml version="1.0" encoding="utf-8"?>
[code].....
(Actionscript 2 btw - and actually cs4, not that it really makes any difference?) I have a class that instantiates a movieclip from the library, e.g.:
Code:
debugbar:MovieClip = thing.AttachMovie("debugbar", "debugbar_mc", 999);
So attaching it to the where ever "thing" is - could be movie clip or level0 or whatever, doesn't matter as "debugbar" is a private variable of the class. Now the important part - debugbar in the library is a movieclip that contains some components - buttons and textInputs. The problem comes when trying to access these components.
I would have thought that this would work:
Code:
debugbar.input_txt.text = "hello";
In order to set the text of "input_txt", the instance name of a TextInput component on the timeline of the movie clip (put there in author time). However, this does not work. Infact, I cannot access any specific "component" properties - they come back undefined. I can however set and retrieve MovieClip properties for the "input_txt", such as _x. However there is one added strange thing with this too - setting _visible to false doesn't seem to work (however perhaps a component by default overrides this).
I also appear not to be able to add event handlers to the component - at least for the usual component events. I tried casting it to a component, such as:
Code:
var temp:TextInput = TextInput(debugbar.input_txt);
trace(temp);
which gave "temp" as null.
However if you trace the thing itself without casting to what it is, it gives the path to correctly. It almost seems like the components are somehow broken when trying to access them this way - or that they cannot be accessed this way?
The thing is, I was able to access all of this before, when the code to do it was placed on the timeline (frame 1, the only frame) of the debugbar itself, where the components were child instances. This meant I could just reference them directly too - so input_txt rather than debugbar.input_txt , although that is probably largely irrelevant. I need to have it in a class though, as I need to pass in certain objects that need to be accessed by the mc.
I'm trying to pass some properties to a component I've created in Flash Builder 4. In my example below I want to pass the "label" property to update the label property of the Button.
// MyApp.mxml

I have written a piece of code where I have created a custom class containing some of my custom properties.I have used multiple instances of this custom class in my main class and added it to a container.Now I need to access one of my custom property in the main class through container.getChildByName()."custom property", but I am not able to access my custom property using this.I get an error saying
Access of possibly undefined property orientation(this is my custom property) through a reference with static type ..name of my main class.
Is there no way that can i access custom property of components through the getchildbyname method of the parent container ??
Would anyone know how to customize the "tooltip" / mouseover popup window in a Candlestick Component?By default, It just displays open / high / low / close data, but I need to add additional details such as date, time, and a few others...I'm guessing this is simple one, using item renderers maybe, but I cannot seem to get my head around it, or find any decent documentation online..

In this case, the 'myButton' component never shows up, but all the elements of the base component do (3 buttons and a datagrid).
I would like to bind two components with out binding and which resides in different MXML.for eg: A.mxml has textinput and B.mxml has a combobox when choose one item in B.mxml selected item should be display in A.mxml textinput.

I'm doing some work with JSON in as3 using as3corelib (very useful) and was wondering if it is possible to get an object if all you have is one of its properties, also an object. Here's an example of some JSON:
"parentObject": {
"propertyObject": {
etc.
}
}
so what i'm asking is, if I have propertyObject, can I access parentObject somehow?
I am working on setting up some simple AI actions for my enemy class in the game that I am working on, but I am having trouble accessing the player's X location within the enemy package to set up a detection function. I have defined the player on my Level package along with the enemy, and I defined the player's and enemies X and Y locations within the Player/Enemies package respectively.
Within my flash file I have linked to my Level.as file. Also within my flash file library I have two movie clips. Both have a square in them that are the same size but colored differently. One is called PlayerSpriteMC and the other is called EnemiesSpriteMC.
[Code]...
I have two movie clips on the stage at frame 1 and frame 2. Both are instances of seperate classes. (They are not dynamically created, just their linkage is set to their class names)I have created soundChannel and Sound Objects in Class 1 and I want to access them from Class 2. (I want to stop the sound channel that was started in class 1)Is there any way to do this? If yes, will this be true for other properties also?

But I never see the "game clicked: " trace. Does anybody please know why? I'm probably missing something minor, because I can see the "Clicked: 8946" trace.
This is similar to the question asked here. I am dispatching custom event "ShopEvent" but i am getting error "Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent"Note: Error is thrown from the parent custom component (3rd code snippet), I have added more details thereThis is my custom event.

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I seem to be having a bit of a problem here. I'm generating a load of class instances using the following code:
maxpersons=25;
for (var i:Number=1;i<=maxpersons;i++)
{
var person:Person = new Person;
[Code].....
OK. I then need to run through each of them and check for a collision with an object from the main stage (called redDot), which I pass to a method (called doDamage) within the class. I'm using the following code:
for (i=1;i<=maxpersons;i++)
{
if (game.getChildByName("person"+i).hitTestObject(red Dot))
{
game.getChildByName("person"+i).doDamage(redDot);
}
}
I keep getting an error saying "1061: Call to a possibly undefined method doDamage through a reference with static type flash.displayisplayObject."!
It just won't work. I've tried altering the code to:
game["person"+i].doDamage(redDot);
but I get an unexpected trace output saying "TypeError: Error #1010: A term is undefined and has no properties."
Is it possible to access variables or even functions of an embedded SWF? (One which has been embedded manually and has not loaded from somewhere)For example, I embed an swf called Movie1 which contains a string variable declared in its root, would it be possible for the parent SWF to access that string?

Maybe I'm not doing it correctly? This is how I've been accessing document class properties so far. Does the fact that they're private make a difference?

I have written "components" in external .mxml files like dialogs and such. For example, GamePropertiesDialog.mxml. These components are used by another file, Main.mxml for example. If I instantiate a GamePropertiesDialog I am unable to access its pieces like a textbox with an id of GameName until AFTER I add the dialog to the display list.Doesn't work:
Actionscript Code:
var tmp:GamePropertiesDialog = new GamePropertiesDialog();tmp.GameName.text = 'test';addChild(tmp);
Does work: Actionscript Code:
var tmp:GamePropertiesDialog = new GamePropertiesDialog();addChild(tmp);tmp.GameName.text = 'test';
I'm currently working on an interactive app, (site) which requires me to modify a few textfields, and change images dependant on the user choice (using mouseevent). This is a separate module, thus I'm posting the question in here instead:there are three images, that are lined up, with a textbox next to them. When a image is chosen, and enlarges, the text changes with the chosen image, according to XML.The textFields, 'text_title', 'text_description' are contained in a movieclip, called 'textbox'.This has been built in the Flash IDE (CS3) named info.fla/swf, which refers to a Document class 'com.info', made in Flex Builder 3...I attempted to modify the textfields using this:textbox.txt_title.text = "Loading";textbox.txt_desc.text = "test";But, I was unable to at first to change the text using the document class, as it gives "1120: Access of undefined property <variable>".
View 3 RepliesIn actionscript an object's property can be accesses in this way: object["propertyname"] Is something like this possible in c#, without using reflection?
View 2 RepliesI have an engine I created a while back that loads objects into a container based on XML data. A really quick example of the XML would be like this:
<level>
<object cname="enemies.Robot">
<pos x="200" y="400" layer="mobiles" />
</object><object cname="Player">
<pos x="12" y="89" layer="mobiles" />
</object></level>
I have a class Environment that has a method loadLevel(data:XML) which I parse the XML through, then the function runs through the XML finding all object nodes and uses getDefinitionByName to determine which Object I want to create based on object.@cname. From here, I have to manually define each property based on the XML like so:
obj.x = xml.pos.@x;
obj.y = xml.pos.@y;
etc.
I was wondering if there's an inbuilt method for setting a property based on a String. By this I mean something like so:
var mc:MovieClip = new MovieClip();
mc.someInbuiltFunctionThatSetsAProperty("alpha", 0.5);
This way I could change my XML to be more like so:
<object cname="Player">
<props>
<x>200</x>
<y>221</y>
<alpha>7834</alpha>
<health>Something</health>
<power>3</power>
</props></object>
And iterate through all the children of props to set all of my properties on the fly. I know if I create an Object and set properties within it like so:
var obj:Object = {
var1: "hello",
var2: "there",
name: "marty"
};
That you can then iterate through names/values using the for(String in Object) loop like this:
var i:String;
for(i in obj){
trace(i + ": " + obj[i]);
}
/**
* Output:
* var1: hello
* var2: there
* name: marty
*/
Surely there's a way, as here's an example of identifying a property using a String:
var ar:Array = [new MovieClip(), new MovieClip()];
ar.sortOn("alpha", Array.ASCENDING);
So just to make my question more to-the-point: I want to be able to get and set properties that I can identify using a String.
I am trying to access the x and y properties of the stage so I can set an objects' x and y properties to place it on the center of the stage:
